Review on 🚗 Portable Bluetooth 5.0 Car Adapter by KINDRM - Stereo Output Receiver for Hands-Free Calls & Mini Wireless 3.5mm Aux Adapter - Black by Eric Kim

Of course I didn't have high hopes for a $10 receiver, but I'm sending it back. It's small, so I can forgive the battery life for not lasting all day, but there's also no (or not enough) shielding, so plugging it in generates a lot of feedback during use. If that were the extent of the problems, it would be good as a short-term portable adapter. However, every time it connects while playing, it shows up as a new device that I need to connect. Pressing the play button is often out of sync when I'm going out of range and coming back. The maximum volume seems lower than other devices. And if you wiggle it a little (or press the controls) you risk jarring the input, which won't line up exactly and will remain static until you wiggle it back.
